IMPRovED'winnLAS-s.

Specification forming' part of Leiters Patent No. 36,870, dated Noveniherji, 1362i Beit known that I, JoEnSfroNE, of Cleveland, inthe county of Cuyahoga and State of Y Ohio, have inventednew and useful Improvements in Vindlasses forGeneral Purposes; and I do hereby declare that the lbllowingiis a l'ull and complete description of the construe` tion and operation of the same, reference being hadto the accompanying drawings, inaking` partei' this specitication, in which f1-`ignre`1isa top view, Fig. 2 is an end view.` Fig. 3 isa crosssection, andFig. 4 is vertical section. i

i BIyinvention relatos to the construction of a windlass for general purposes, whether on shipboard, in warehouses, on buildings, or ou farms. i i

The windlassas awhole consists cfa drum, y

two `gear\\'l1eels,`one near each end, two eudless screws, pawls and ratchet, and a suitable frame-work` y The posts that support the windlassdrum are shown at A. `These may consist of a singie plank `or a frame-work in thc form` of a Brepresents the windlass-drnm or horizon- .tal capstan. `Upon the shaft oi' the drum, and outsideof the frame on both ends, is a set of pulleys() C,ifor raising light weights in i warehouses, &c; In the middle of the drum B is a ratchet, D,which may be supplied with a pawl, to prevent the drum from'turning backward in raising light weights. i i

E E,`Figs. 2, 3, and 4, represent gear-wheels, which run loosely upon the shaft of the windlass-drunnand are connected withthe drum by a pawl,` F, attached to thewheelsE, and a ratchet wheel, IW, upon the windlass shaft; consequently the windlassshaft can always be turned in one direction independent of the movement of the gear-wheels.

\ G G represent endless screws, which work in the icoggears, as seen in Fig. 8. screwsare-placed at right angles to the shaft of the windlass and above the coggear wheels E E. The endlessscrews areturned by -means of pins or arms ,placed in the holes H ,at each end of the screws'and outside of the framework.

In raising heavy weights thecablle` o1' rope i VFandslowly but powerfully rotate the windlass.

Either one or both screws may be caused to act at the same time, which will be necessary in raising very heavy weightspbut for ordi'- nary purposes one screw will `be suflicient. The movement of each is independent of the other, and as long asthe pawl is in contact with the teeth of the ratchet the shaft of the windlass cannot turn backward.

` What I claim as thy-improvement, and del sire to secure byLetters Patent isV The use of the two horizontal screwsl G G, constructed and actuating the windlass B, substantially as described, the windlass having at its extremities a succession of pulleys or groove, C, as set forth.
